Investigation of potential ultra-low $Q$-value $β$-decay candidates $^{89}$Sr and $^{139}$Ba using Penning trap mass spectrometry
R. Sandler, G. Bollen, N. D. Gamage +6
The authors used Penning‑trap mass spectrometry to precisely measure the masses of 89Y and 139La, derived the beta‑decay Q‑values for 89Sr→89Y and 139Ba→139La, and showed that the…

Excited states of the odd-odd nucleus 158Eu from the (d,alpha) reaction
D. Bucurescu, S. Pascu, T. Faestermann +7
The paper reports the identification of more than 50 excited states in the odd‑odd nucleus 158Eu up to 1.6 MeV using the 160Gd(d,α)158Eu reaction measured with a Q3D spectrograph.

Analysis of Bohr formula of momentum of inertia for even-even atomic nuclei
Mohd Kh. M. Abu El-Sheikh, Abdurahim Okhunov
The paper re‑examines the Bohr formula for the moment of inertia of even‑even deformed nuclei by including the first three terms of the radius expansion, leading to results that be…
